Scraps of DNA discarded by our neurons' power units are being absorbed into our nuclear genome far more frequently than assumed, potentially putting our brains at greater risk of developing ...

Mitochondria release segments of mitochondrial DNA that can travel through pores of the nucleus and integrate into a cell's chromosomes (where the insertions are called NUMTs, for nuclear ...

Scientists have found DNA in the nucleus of brain cells, where it shouldn’t be. Bits of genes that typically reside in mitochondria insert themselves at unexpectedly high rates into brain cells’ ...

Researchers have discovered a key molecular process that may contribute to chronic inflammation as we age. If this process can be accurately targeted, it could unlock ways to stay healthier in our ...

The structural and functional characteristics of mitochondria shape their role as signaling organelles, with far-reaching ...

The tiny little powerhouses of our cells: mitochondria, are unique among organelles because they carry their own tiny little genomes. This genetic material is separate from the rest of our genomic DNA ...

It’s one of the basic tenets of biology: We get our DNA from our mom and our dad. But one notable exception has perplexed scientists for decades: Most animals, including humans, inherit the DNA inside ...

Normal metabolic activity produces reactive oxygen species (ROS) that, if not eliminated, can damage cellular components. As a result, ROS from overactive mitochondria are frequently cited as a source ...

How One Tiny Cellular Structure Holds the Key to Better Health & Longevity — and How You Can Harness It ...

In a step toward treating mitochondrial diseases, researchers at the University Medical Center Utrecht and their colleagues have used mitochondrial base editing (mtBE) to successfully edit harmful ...
